2 construction and combinations of parts here- Referring now particularly to Figs. 7 and inafter described and claimed. 8, the ventilating unit therein illustrated In the drawings: comprises a series of shutters working on Figure 1 shows a face view of a. window horizontal pivots or axes within a selfframe having a plied to its bottom portion contained frame having side members 16 and 3 a ventilator embodying the features of the 17 a top 18, and a bottom 19. These shutpresent invention; ters are set in pairs opposite to each other,

Fig. 2 shows a, fragmentary detailed view as shown in Fig. 7, each pair comprising of the operating mechanism for a pair of shutters 20 and 21. Each shutter is convenshutters in fully opened position; iently made from sheet metal or other suit- 35 Fig. 3 shows a. view similar to Fig. 2, able material and is mounted on a horizontal with the exception that the shutters are in bar 22 pivoted in the side members 16 and a fully closed position; 17: The upper end 23 of each shutter is Fig. 4 shows a view similar to Figs. 2 and preferably curved or bent outwardly, and 3, with the exception that the closing of the its lower end 24 is preferably curved or bent 40 pair of shutters connected to the operating inwardly, as shown in Fig. 7. This arrangemechanism illustrated in this figure has been ment is such that when the shutters are fully interfered with by the presence of some opened their upper ends 23 will come toobstruction; get-her, whereas when the shutters are fully Fig. 5 shows a modified application of the closed, as shown by dotted lines, the upper 45 features of the present invention to a tranend 23 of each shutter plate will come into som shutter above a door; register with the inwardly curved or bent Fig. 6 shows a vertical section through a lower end of the next higher shutter so as frame within which has been installed the to provide an air tight and dustproof ventilator of the present invention,the parts closure, as shown by the dotted lines.

50 standing in open shutter position; It is preferred that the upper portion of t Fig. 7 shows a vertical section through the the frame be provided with a pair or hori ventilator, embodying the features of the zontal bars 25 and 26, as shown in Fig. 7, present invention, the shutters being shown so as to effect a satisfactory closure at this 29, and the shutter 28 being pivoted on the axis 30. This arrangement is such that when these two shutters are thrown into. the open or dotted position a straight opening is provided through the lower portion of the frame to make it possible to remove dust and dirt'which may have collected therein.

On one end'of the frame is provided ashutter operating mechanism, as shown in Figs. 6 and 8. I will now describe the same in detail. 'Each pivotal bar 22 is carried through the end member 16 of the frame and is provided with an operating lever or finger 31. The movement of these levers serves to rock the shutters. A vertical operating bar 32 is slidably mounted adjacent to the'member 16. being guided in its movements by the clips or guides33 and 34, as shown in Fig. 6. Said operating bar 32 carries a slotted plate corresponding to each of the levers: or fingers 31. each plate 35 having alongitudinal slot 36. Each'finger or lever 31 carries a pin 37 working in the corresponding slot 36, the arrangement being such that when the plate 32 is drawn downward to the full extent the fingers 31 will be rocked towards each other by the engagement of their pins 37 with the extreme end portions of the slots 36 so as to fully open the shutters.

A spring 38 is provided between 'ach plate 35 and the corresponding pin 37, s id spring tending at all times to. rock the corresponding finger 31 outwardly so as to close the shutter. The desirability of this arrangement will be understood from the following explanation: If a foreign body should be lodged between two of the shutters in vertical alignment so that they could not be fully closed. the closing of all of the other shutters would be interfered with and prevented, unless some form of ,lost motion connection such as the slotted connections were provided. The springs 38 tend to carry the individual shutters into the closed position, but in case of interference by a foreign body two or more of the shutters may remain in open position Without interfering with the closing of the remaining shutters.

The operating lever 12 is conveniently pivoted to the window or door casing at the point 39. as illustrated in Fig. 6. This lever and the slotted plate 13 may be installed as a portion of the permanent equipment of the building. In like manner the shutter unit may be installed as a portion of the permanent equipment. Inasmuch as the operating connection must be provided between the lever and the shutter mechanism, and inasmuch as this operating connection must-be so adjusted that the shutters will 1 upper and lower ends 43 and 44:, respectively, of the bar 32. The lower end of the rod 42 is connected to the lower end 44 of the bar in an adjustable manner by means of set nuts or the like 45 threaded onto its lower end, and by means of which the plate may be raised or lowered with respect to the I rod 42 and set into desired position.

When the ventilator unit is located in a position easily accessible, as in a wall, partition or door, the operating handle 12 is exposed in the face of the unit, but when in an unaccessible place, such as a sky-light, near a ceiling, or as shown at 10, beneath a window a suitable connecting rod 40 runs to an accessible point where the handle 12 operating in the plate 13 is placed, the'object also being to have the operating handle at a point on the level with the shoulder.

I claim: v
